I get "Not a genuine Lenovo Battery" message only sometimes

2011-04-04, 22:55 PM
I'm not sure whether my battery is genuine or not, it doesn't say "Lenovo" on the bottom, nor does it say anything on the bottom at all, but every now and then (like 1 in every 3 times I power up my Thinkpad) this message pops up and tells me "the battery installed is not a genuine Lenovo battery." It's annoying and intrusive, but shutting down and restarting seems to get rid of the problem. It's so confusing too, since I've had this battery for months now and only recently has it been acting up like this. I bought the battery off of Amazon.com for about $60, which would make me think it's indeed NOT a genuine Lenovo battery, but it works just fine for me and I've never had problems with it until about three weeks ago, when this all started. My guess is the problem is aggravated by the battery not being seated firmly enough in the laptop, because admittedly the battery is somewhat loose in its mounting. I actually AM beginning to think it's not a genuine battery, but why would it only tell me so SOMETIMES? And why did my laptop accept my battery for months up until now? Is there anything I can do?

Hi adept25,

I believe if you uninstall Power Manager, the notification would stop.

In regard to genuine, one way to tell is by searching the FRU part number (that the Power Manager shows) on lenovo's website:- http://i53.tinypic.com/noeao6.png

Hope this helps.

what is the brand and make of your new battery's cells? also does the serial no. on the battery pack matches with the one printed on the barcode that is stuck to the laptop.

If it doesn't say IBM or Lenovo on it, it isn't
